Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a traditional railing system is used that requires multiple individual posts to be secured and disassembled, then the railing system can be securely attached to flatbed trailers, but the installation and reconfiguration process becomes slow and time-consuming

Engineering Contradiction:
ImproveInstallation speedVSAvoidNumber of individual posts requiring assembly
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Multiple individual posts are merged into a single integrated mobile railing assembly that includes a frame structure with multiple vertical posts connected by horizontal members. This assembly moves as one unit on casters, eliminating the need to separately handle and secure multiple individual posts during installation and reconfiguration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mobile railing assembly is designed with universal applicability to fit various flatbed trailer sizes and configurations. The adjustable height mechanism and standardized connector system enable the same assembly to be rapidly adapted to different trailer types, enhancing productivity across diverse applications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a fixed railing system is used that is designed for specific trailer sizes, then the railing can be securely attached, but the system lacks flexibility for use on a variety of different sized flatbed trucks

Engineering Contradiction:
ImproveCompatibility with various trailer sizesVSAvoidTime required to reconfigure for different trailers
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The railing assembly incorporates adjustable height mechanisms on the vertical posts, allowing the structure to be dynamically reconfigured to match different trailer heights and sizes. This dynamic adjustability enables rapid adaptation to various flatbed configurations without requiring multiple specialized assemblies.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mobile railing assembly is designed with universal applicability to fit various flatbed trailer sizes and configurations. The adjustable height mechanism and standardized connector system enable the same assembly to be rapidly adapted to different trailer types, enhancing productivity across diverse applications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If individual posts are secured and disassembled with each flatbed trailer, then the railing system can be properly attached to each trailer, but the process becomes time-consuming and reduces operational efficiency

Engineering Contradiction:
ImproveSecure attachment to trailerVSAvoidTime spent on assembly and disassembly
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Multiple individual posts are merged into a single integrated mobile railing assembly that includes a frame structure with multiple vertical posts connected by horizontal members. This assembly moves as one unit on casters, eliminating the need to separately handle and secure multiple individual posts during installation and reconfiguration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The railing posts are pre-assembled into a complete frame structure before deployment. This preliminary assembly ensures structural integrity and reliability while eliminating the time-consuming process of assembling individual posts on-site during each installation.

Inventive Principle:
Principle #10Preliminary action

AI summary

A railing assembly for use with a flatbed trailer is disclosed. The railing assembly includes cooperable posts extending in an upwardly direction and a plurality of elongated members extending laterally between the cooperable posts. Each of the cooperable posts is supported on a caster system that includes a plurality of casters enabling rolling movement of the railing assembly relative to the flatbed trailer. A connector system is slidably engaged with any of said cooperable posts enabling adjustment of the height of the connector system. The ability to adjust the height of the connector system enables engagement with a variety of flatbed trailer having varying heights and sizes for securing said railing assembly to the flatbed trailer.
